Political turmoil has cast a shadow over Turkey, but Japanese conglomerate Mitsubishi told CNBC the country remains an attractive investment destination.

Turkey's ruling party - the AKP - which has been in power since 2003, was hit by a high level bribery and corruption scandal which sparked street protests late last year. More recently, Prime Minister Tayyip Erdogan temporarily banned social media site Twitter, provoking international criticism about the country's control on freedom of expression.
